Description
Diagram of a weight hung at the bottom of a bladder, whose neck is fastened to post. The bladder can be inflated through a quill inserted at the top. As the bladder is inflated the weight is raised. This diagram was in William Croone's paper, which was presented to the Royal Society on 6 November 1661. This was further discussed by John Wallis on 4 March 1663.
